  • the top sheet 10 is joined to the absorbent 30 using, for example, a hot melt adhesive.
  • coating patterns of the hot melt adhesive on the top sheet 10 or the absorbent 30 include a parallel line pattern in which parallel lines extending in the lengthwise direction are arranged in parallel at prescribed intervals in the widthwise direction, a band pattern in which bands extending in the lengthwise direction are arranged in parallel in the widthwise direction, a wavy pattern in which wavy lines having an amplitude in the widthwise direction and extending in the lengthwise direction are arranged in parallel in the widthwise direction, or a spiral pattern in which spirals extending in the lengthwise direction are arranged in the widthwise direction.

  • the material of the side sheet 40 is preferably hydrophobic or water-repellent.
  • a spun bond non-woven fabric or spunbond/meltblown/spundbond (SMS) non-woven fabric, for example, can be used for the side sheets 40. Since the side sheets 40 contact the skin of the wearer, an air-through non-woven fabric is preferably used.

  • styrene-based block polymers used for the pressure-sensitive portion 50 include styrene-ethylene-butadiene-styrene (SEBS) block copolymer, styrene-butadiene-styrene (SBS) block copolymer, styrene-isoprene-styrene (SIS) block copolymer and styrene-ethylene-propylene-styrene (SEPS) block copolymer.
  • SEBS styrene-ethylene-butadiene-styrene
  • SBS styrene-butadiene-styrene
  • SIS styrene-isoprene-styrene
  • SEPS styrene-ethylene-propylene-styrene
  • Examples of natural resin-based adhesion-imparting resins include terpene-based resins such as copolymers of ⁇ -pinene, ⁇ -pinene or dipentene, rosin-based resins such as gum rosin, tall oil rosin or wood rosin, and hydrogenation products or esters thereof.
  • examples of synthetic resin-based adhesion-imparting resins include aliphatic (C5) petroleum resins, aromatic (C9) petroleum resins, copolymer-based petroleum resins, hydrogenated petroleum resins, DCPD-based petroleum resins and pure monomer-based petroleum resins.
  • examples of plastic materials include paraffin oils that decrease viscosity, naphthene oils that increase tackiness, and aromatic oils that decrease cohesion or impart color or odor.
  • the coated basis weight of the pressure-sensitive adhesive of the pressure-sensitive adhesive portion 50 is 10 to 100 g/m 2 and preferably 20 to 50 g/m 2 . If the basis weight is less than 10 g/m 2 , the adhesive strength of the absorbent article 1 may end up weakening, the absorbent article 1 may end up not attaching to an undergarment such as underpants, the absorbent article 1 may end up falling or shifting during use, or may end up causing discomfort for the wearer.
  • the adhesive strength of the absorbent article 1 may end up being excessively strong, the absorbent article 1 may be torn when the absorbent article 1 is peeled from an undergarment such as underpants, or a portion of the absorbent article 1 may become attached to an undergarment such as underpants and be unable to be peeled off, thereby making this undesirable.
  • a band-shaped airlaid non-woven fabric 212 is fed from an airlaid non-woven fabric roller 210 on which is wound the airlaid non-woven fabric 212.
  • Crushed pulp 222 is fed from a crushed pulp supply device not shown to a pattern drum 220.
  • Indentations 224 are formed in a shape that packs the crushed pulp on the outer periphery of the pattern drum 220.
  • Suction 226 is generated within the pattern drum 220, and the crushed pulp 222 fed to the pattern drum 220 is suctioned into the indentations 224 and compressed.
  • a crushed pulp layer 228 formed within the indentations 224 is layered onto the airlaid non-woven fabric 212 and joined with a hot-melt pressure-sensitive material resulting in the production of an absorbent 232 composed of the airlaid non-woven fabric 212 and the crushed pulp layer 228.
  • the absorbent 232 is cut into individual absorbents 234 by making cuts to the front and back of the absorbent 232 with an absorbent front and back-cutting cutter 240.
  • Each of the absorbents 234 is covered with a top sheet 252 supplied from a top sheet roller 250, and the top sheet 252 is joined to the absorbent 234 by using a hot-melt adhesive.
  • side sheets 262 are fed from a side sheet roller 260 and arranged on both sides of the top sheet 252 so as to overlap with respective side portions of the top sheet 252.
  • the absorbent 234 is compressed in the thickness direction using an embossing device 270 to form a plurality of indentations extending from the top sheet 252 to inside the absorbent 234 and a plurality of indentations extending from the side sheets 262 to the absorbent 234 through the top sheet 252 in a laminate 236 comprised of the side sheet 262, the top sheet 252 and the absorbent 234.
  • the following provides an explanation of an upper roller 272 and a lower roller 274 of the embossing device 270 with reference to FIG. 4 .
  • pins 276 are provided on the upper roller 272 at locations corresponding to the indentations 60 and 70 (see FIG. 1 ) provided in the absorbent article 1.
  • the shape of the pins is flat with the exception of a conical tip.
  • projections 278 are provided on the tips of the pins 276 corresponding to the indentations 60 of the central portion of the absorbent article 1 in order to form the highly compressed portions 62 (see FIG. 2 ) of the indentations 60.
  • the diameter of the tips of the pins 276 is preferably within the range of 0.5 to 6.0 mm, and more preferably within the range of 1.0 to 2.5 mm in consideration of the balance between rigidity and flexibility of the absorbent article 1.
  • the laminate 236 is unable to be adequately compressed, while if the diameter is greater than 6.0 mm, the laminate 236 is compressed excessively, which may end up causing the laminate 236 to be excessively hard. As shown in FIG. 4(c) , projections such as pins are not formed on the lower roller 274.
  • a back sheet 282 fed from a back sheet roller 280 shown in FIG. 3 is adhered by overlapping the surface of the embossed laminate 236 on the side opposite from the top sheet side to form a continuum 238 of the absorbent article.
  • the continuum 238 of the absorbent article is cut into the shape of an absorbent article using a cutter 290 to produce the absorbent article 1.
  • the individual absorbents 234 are obtained by cutting the adsorbent 232 in the front and back with the absorbent front and back-cutting cutter 240 in the aforementioned steps.
  • individual absorbents may also be obtained as a result of cutting the continuum 238 of the absorbent article into the shape of absorbent articles by using the cutter 290 instead of using the absorbent front and back-cutting cutter 240.
  • the absorbent article 1 of an embodiment of the present invention as described above demonstrates one or more of the actions and effects indicated below.
  • the present invention encompasses the following absorbent article which is set out in clauses defining features of the invention.
